Amyloid β-Protein (1-28)/109770-29-8 /GT Peptide/Peptide Supplier

Kufotokozera

β-Amyloid (1-28) ndiβ-chidutswa cha amyloid chomwe chingathe kutenga nawo mbali pomanga zitsulo.Beta-amyloid ndi peptide yomwe imapanga zolembera za amyloid muubongo wa odwala omwe ali ndi matenda a Alzheimer's.1. Sungunulani cholimba Aβ peptide mu ozizira hexafluoro-2-propanol (HFIP).Ma peptides adakulungidwa kutentha kwapakati kwa 1 h kuti akhazikitse monomerization ndi randomisation ya zomanga.2. HFIP idachotsedwa ndi evaporation ndipo peptide yotulukayo idasungidwa ngati filimu pa -20 kapena -80° C. 3 Zomwe zimapangidwira zinasungunuka mu 5mM anhydrous DMSO ndipo kenako zimagwedezeka ndi kuchepetsedwa kuti zikhale zoyenera komanso zowonongeka (zapakati zopanda seramu ndi phenol zofiira).4 Kenako, yankho linali lazaka 4-8° C kwa maola 48.Zitsanzozo zidasinthidwa kukhala 14000g kwa mphindi 10 pa 4-8.° C. Oligomeri osungunuka anali mu zauzimu.Wamphamvuyo adachepetsedwa 10 mpaka 200 kuti ayese.

FAQ:

Ndi malingaliro otani ndikayamba kugwiritsa ntchito ma peptides?

Mukakonzeka kugwiritsidwa ntchito, tsatirani njira zomwe zili pansipa kuti musungunule ma peptides kuti akhalebe abwino.

1, musanatsegule botolo ndikuyesa gawo la peptide, litenthetseni kuti lifike kutentha, ndipo nthawi yotentha imayenera kukhala ola limodzi.

2. Yezerani mwachangu kuchuluka kofunikira m'malo oyera akunja.

3. Sungani ma peptides otsala mufiriji pansi -20℃, onjezerani ma desiccants ndikuwasunga mu chidebe chopanda mpweya.

Ndimakhala kunja, ndipo zidzatenga masiku angapo kuti ndiperekedwe ndi chilolezo cha kasitomu.Kodi izi zikhudza kafukufuku wanga?

Mumalandira peptides mu lyophilized ufa phukusi, ndi peptides nthawi zambiri kusungidwa firiji popanda kuwonongeka.Chonde ikani ndikusunga mukangolandira.

Ndi mavuto ati omwe ayenera kutsatiridwa posungirako?

Peptide yomwe mudalandira idayikidwa mu ufa wa lyophilized.Ma peptides ndi hydrophilic, ndipo kuyamwa kwa madzi kumachepetsa kukhazikika kwa peptide ndikuchepetsa zomwe zili ndi peptide.Chonde tcherani khutu ku izi: choyamba, ndi desiccants, zosungidwa pamalo owuma.Chachiwiri, kamodzi analandira, chonde yomweyo kuika mu mufiriji -20℃kusungirako, kuti mukhalebe okhazikika kwambiri.Chachitatu, pewani kugwiritsa ntchito mufiriji wopanda chisanu.Kusintha kwa chinyezi ndi kutentha kumatha kukhudza kukhazikika kwa ma peptides.Chachinayi, kutentha kwakunja panthawi yoyendetsa sikukhudza kutsimikizika ndi khalidwe la peptides.

Kodi ndimasunga bwanji ma peptide owumitsidwa ndikalandira malonda?

Mukachilandira, muyenera kuchisunga nthawi yomweyo pa -20° C kapena pansi.

Ngati peptide ili 80%, 20% ina ndi chiyani?

Mchere ndi madzi

Ngati peptide ndi 98% yoyera, 2% ndi chiyani?

Awiri peresenti ya zolembazo zinadulidwa kapena kuchotsedwa zidutswa zotsatizana.

Kodi AMU unit ndi chiyani?

AMU ndi gawo la micropolymerization.Ichi ndiye muyeso wamba wa peptides.
